Antwerp Central train station is located within a fifteen-minute walking distance from the conference location at the City Campus.
You will find more information on the Belgian railway system here, including a route planner.
For those who will be travelling by plane to the Brussels/Zaventem airport, a cheap alternative to taking the train to Antwerp is the Airport Express. This will take you to De Keyserlei in 40 minutes, right next to Antwerp Central train station and in walking distance from the City Campus.
The best way to get to the conference venue from Antwerp Airport is by bus. Bus 14 stops directly at the entrance of the airport, and will take you straight to Rooseveltplaats (only five minutes away from campus). The penultimate stop of bus 14 is Antwerp Central station. Make sure to take the bus that says "Rooseveltplaats," not "Vremde - Mortsel."
